Beta-Pix (Cool-1) associates with CBL, which appears to be a critical step in CDC42-mediated inhibition of EGFR ubiquitylation and downregulation. The SH3 domain of Beta-Pix specifically interacts with a proline-arginine motif (PxxxPR) present within CBL, which mediates ubiquitylation and subsequent degradation of Beta-Pix.
